I cannot find any example, post, or video that clearly shows what Global Replacement Variables are best used for and how to use them (ideally in the query unless they aren't meant to be used here)? I think a solid definition of what the difference is between a 'Replacement Variable' and a 'Global Replacement Variable' would help quite a bit as well!
Ex: Lets say I want to use a Global Replacement Variable to limit multiple Job's query's where clase to include all data since the beginning of 2019, is that a use case for Global Replacement Variables?
SELECT *
FROM dbo.employee
WHERE startDate >= <Global Replacement Variable with correct syntax that reprensents 2019-01-01>
